Do the voters care about PRISM? You Gov Poll - Carry on Spying

I have just come across the results of a You Gov Poll which indicates that the majority of the public thinks that the security services are merely doing what we pay them to do. That majority is consistant across all groups, albeit weakest among the young and among labour voters. Also, for most groups, the proportion thinking that it is not only normal but that they would be disappointed if we British did not spy on others at international conferences, outweighs the don't knowns and "would rather we did not" added together.
